摘　　要：针对含分布式电源的配电网通信问题,考虑专用无线网络或光纤方式实现通信全覆盖的难度较大,且易出现数据传输受阻情况。基于5G搭建配电网通信系统,引入安全网络编码策略构建电力数据传输的安全策略,通过设计密钥分发流程,实现对通信过程中数据信息包的隐私保护,有效解决通信系统易受干扰和攻击的问题。验证结果显示经安全策略压缩加密后的数据曲线与原始数据曲线之间具有较大差异,攻击方无法获取到准确的原始数据,同时安全策略可有效抵御数据拦截等攻击情况,保护含分布式电源的配电网通信系统的安全性与隐私性。For the communication problem of power distribution network containing distributed power supply,it is difficult to consider dedicated wireless network or optical fibre to achieve full coverage of communication,and it is easy to appear data transmission obstruction.The communication system of distribution network is built based on 5G,and the security strategy of power data transmission is constructed by introducing the security network coding strategy.By designing the key distribution process,the privacy protection of data packets in the communication process is realized,which effectively solves the problem of the communication system being susceptible to interference and attack.Verification results show that the data curve compressed and encrypted by the security strategy has a large difference between the original data curve,the attacker is unable to obtain accurate raw data,and at the same time,the security strategy can effectively resist the attack situation such as data interception,and protect the security and privacy of the communication system of power distribution grid containing distributed power supply.
